Title: Method and apparatus for uniform processing
Inventor: AIDA TAKASHI
IPC: H05H1/46
Filed: 1989-03-30
Abstract: PURPOSE:To execute an ultraine processing operation and a uniform processing operation by a method wherein a peak part of distribution of an ion current density is moved, by using a composite magnetic field of a main coil and an auxiliary coil, on the surface of a specimen while this surface is being processed. CONSTITUTION:A gas which has been introduced into an ionization chamber from a gas introduction port is transformed into a plasma by microwaves introduced from a waveguide and by an electron cyclotron resonance through an action of a main coil 8. This plasma becomes an ion stream by a divergent magnetic field formed by the main coil 8, diverges and flows out, reaches a specimen and etches it or is deposited. In this case, an auxiliary coil 9 is attached to the underside (on the side opposite to the main coil) of the specimen; a so-called mirror magnetic field which forms a magnetic field in a direction identical to the main coil 8 is constituted and the auxiliary coil 9 is moved. Since an ion current density is high especially in the central part of the mirror magnetic field, a part whose etching operation is slow is irradiated with this part preponderantly. Thereby, it is possible to improve a uniformity.

Filed: 1979-06-26
Abstract: PURPOSE:To prevent accidents from being generated due to the operation miss for pack medium loading, by detecting the loading state of the pack medium cover to inhibit the start-up operation. CONSTITUTION:When pack medium 6 is put on spindle 7 of the magnetic disc pack unit, inhibiting circuit 5 is operated by cover fitting and removing signal (a) since the light from a light source does not reach the photodetecting element; and when the driving start operation is performed under this state, driving start signal (b) is transmitted, however, the operation of driving start circuit 9 is stopped by inhibiting signal C from circuit 5, and spindle motor starting signal (d) is not transmitted, and spindle motor driving circuit 10 is not operated, and spindle motor 11 continues the stop state. Next, when pack medium cover 1 is lifted and removed after loading of medium 6, the shielded light from the light source reaches the photodetecting element, and therefore, respective circuits are operated normally by this operation. As a result, accidents are prevented from being generated due to the operation miss for pack medium loading.

Abstract: PROBLEM TO BE SOLVED: To obtain high resolving power and a high recording speed by supporting the wt. of a structure by the air bearing pressure generated by a floating head and equilibrating the floating force of the floating head with the centrifugal force applied to the floating head. SOLUTION: A floating head 10 is attached to a locating structure like a bending member 12 and a balance wt. 14 is attached to a pivot arm 16 in the direction opposite to the floating head 10 and the bending member 12. The pivot arm 16 is attached to a rotor 18 by a rotary shaft 20. Light 42 is emitted from the floating head 10 in order to expose a medium 24 and, at the same time, a pressurized air bearing 44 is formed between the floating head and the medium 24. When the rotor 18 is rotated, centrifugal force is applied to the floating head 10 and the floating head 10 moves outwardly toward the medium 24 in a radial direction and air passing through the gap between the floating head 10 and the medium 24 is compressed to form a positive air bearing. By this constitution, the floating head 10 is floated on the surface of the medium 24 at an accurate interval.

Abstract: PURPOSE:To restrain the formation of a laser resonator effectively so as to obtain a stable radiation in an LED mode by a method wherein a light takeout end face and an opposite end face are obtained by cleaving and made to be sloping faces. CONSTITUTION:An n-InP substrate 1 is cut out along a (111) face, and an n-InP buffer layer 2, an InGaAsP active layer 3, a p-InP clad layer 4, and a p-InGaAsP cap layer 5 are successively made to grow epitaxially, on the (111) face.
